P To all whom it may concern:

Be it known that I, Snauron citizen of the United States, residin at Gunntown, in the county of Levy and tate 5 of Florida, have invented certain new an useful Improvements in Automatic Ma chines for Shaping and Fastenin Iron Bands to Box Material, of which t e following is a specification. This invention relates to an automatic machine for shaping and fastening iron bands to box material, such as box-covers.

The object of the invention is automatically to feed the material for making boxes, havmg particular reference to covers, through the machine, and simultaneously feeding metal strips for reinforcing the ends of' the cover through the machine with the cover, shaping the metal strips around the ends of the cover, after which the cover and metal strips are fed through the pressuredies, where the metal strips are perforated and the metal strips and cover pressed together, and finall severingthe stri s and passing the comp eted article beneat a receiving rack, the final 0 eration being to transfer the stacked rein orced covers to a receiving table where they may be compressed and tied for shipment.

Fig. 23 is an enlarged detail view of one of the spring-pressed dogs carried by the reciprocating carriage.

The machine consists of a main frame, comprising parallel side-bars 1, 1 and end members 2 2, sup orted at eac end by suitable ad ustable egs 3. Arranged within the main frame is a reciprocatingicarriage consisting of parallel bars 4, su ported by suitable guideways 5 supported y suita le transfer members 6, 6, arranged across the main frame. The carriage is actuated by means-of a cam 7 keyed to the shaft 8, the latter being earedto the main drivefie gears 10 and 11. The main drive is driven by belt-pulleys '12. The said driving means is journaled in suitable standards 13, 13, mounted u on the base 14, the 11 per ends of said stan ards being connected together b suitable cross-beams15. Arranged longrtiidinall of the machine,

and sup ortedupon the ase 14 is abeam 16,- to Wllcll is ivoted a rockin -beam: 17, the upper end 0 -whichis pivotal y-connected to the reci rocating carriage by means of a yoke18. he rocker-beam-l'f inturn is connected by connecting-rod'- 19 to. .an .ec-"

centric strap 20 which surrounds the eam :7. In: this manner the carriage 1s. given' a constant reciprocating movement.

Arrangedflat the forward endof frame and above the reciprocating carria e 5- in-forcing metal-is ache t 1ied..;mms 23 connect to a foot-lever 27, pivoted as at 28 to the supporting-beam 16. A spring 30 secured as at 31 to one end of the main frame, and as at 32 to the foot-lever 27, serves to hold the arms 23 under tension, whereby the covers are fed downwardly as they are taken from the under side of the pile in the feeding 110pper, as hereinafter described.

When re-filling thehopper, the foot-lever 27 is pressed downwardly, swinging the arm 23 laterally, permitting the hopper being readily re-filled. Extending forwardly of the hopper on each side of the machine is a set ofbending rolls adapted to receive the strips of metal which are to be fed simultaneously through the machine with the covers. The first set of rolls 33 and 34 are pivotally mounted upon vertical studs at a slight angle. the parallel surfaces adapted to receive the metal strips 35 edgewise, as illustrated in Fig. 11. The next set of rolls consists of male and female rolls 36 and 37, so shaped as to bend the metal slightly, as

- illustrated in Fig. 12. The next set of rolls consists of male and female rolls 38 and 39, so shaped as to impart substantially a right-angle bend in the metal band These strips are preferably fed to the machine by a pair of reels 40, as disclosed in The cover to be reinforced is removed from the hopper by asset of spring-actuated dogs 41 carried by the reciprocating (arriage, which, as shown in Fig. 2, are in position to remove the lowermost cover from the hopper. The rearward stroke of the car- 2 riage is so regulated as to carry the cover together with the metal strip 35 a certain distance toward the rear of the machine. The metal strips and the edges of the cover pass through another set of bending blocks 42. These blocks serve as guides for the setof bending-rolls 43 and 44, serving tobend the metal strips at a more acute angle around the edges of the cover. Another set of bending rolls 45 and 46 are placed ahead of the rolls 43 and 44, serving to bend the metal strips 35 more about thekedges of the cover,-

as shown in Fig. 16, and finally the strips and the cover are passed through a set of bending blocks 48, having a substantially U-shaped, opening 49 therein, serving to press the metal strips 35 snugly around the edges of the material as disclosed in Fig. 17.

Arranged at the open end of the U-shaped opening 49 are a set of .upperand lower guide members 50, which serve to position the metal strip evenly around the edges of the cover.

The carriage having traveled a eufiieient ment of the several punches.

distance to place the cover in the position opposite the last-mentioned set. of rolls, moves forward again. The cover, which has previously been placed before the second set of bending-rolls is prevented from mov ng back by suitable stops 51 carried by the main frame. As thecarriage moves forward, another cover is taken from beneath the'pile in the feeding-hopper, and the spring-actuated dogs 52 carried by the reciprocating carriagc in turn move the first cover rearwardly a sufficient distance to place the same beneath a setiof dies, where the metal strips are punched and forced together against the cover.

These dies preferably consist of a set of This beam 60 is guided for vertical movc-- ment in suitable slots in the standards 13,

As clearlyshown in Figs. 18, 19, 20, and

21, the statlonary member 53 of the dies has secured to the upper side thereof a bar 63. Arranged along the inner edge of this bar are a' plurality of punches 64, the lower ends 65 thereof being squared and received in a slot 66 running longitudinally of the member 53, thereby insuring the proper align- A vertically movable stripper bar 67 is arranged directly above the slot 66 normally covering the upper ends of the punches 64, bein held in spaced relation to the member 53 y means of beaded studs 68, the body portions of which are surrounded by spiral springs 69.

A guide-member 70 is arranged longitudinally of the member 53, serving to position properly the box cover and metal strips 35 over the punches 67. Themember 58 carries a similar bar 71 which likewise carries a plurality of punches 72, the inner ends 73' thereof being squared and received in a lon gitudinal slot 74' in the member 58. The outer ends of the punches are likewise protected by a stripper-bar 75' su ported in spaced relation to the member 58 y suitable I recast? ends thereof, which ends are adapted to extend beyond the cover proper, and lrkewise punch holes at intervals along the stripand box cover,"to1:1ning nail holes for finally sefirst-mentioned punches 64 and 72 through tbemetal strip, and into the material, as clearly shown in Fig. 21, the punches, 64 and 72 being slightly offset, as shown in Figs. 20 and 21.

Fig. 22 shows the operation as completed at this point. To assist "in holding the material in place as it is fed beneath the dies, I preferably provide two parallel strips 73, which lie parallel and adjacent to the dies being bent up at one end and secured as at 74: to the transverse bars 75 supported by the standards 13, 13, the cover passing leeneath this strip as it passes beneath the dies. In the last operation, the metal strips 35 having been securely fastened to the edges of the cover, it is, now desirable to sever the continuous strip and stack the different covers after being reinforced. To accomplish this, 1 preferably arrange a plurality of vertical standards 76 securedto the main frame 1, 1, forming an assembling-rack. These standards have ivoted to their extreme upper ends dogs 7. The lower ends 78 of these dogs extend through openings in the standards being held in that pos1- tion by springs 79, as shown in Figs. 8, 9 and 10. I

As illustrated in'Fig. 4, the cover is raised from the carriage a sufficient hei ht to be received by the dogs 77, the following mechanism preferably being used to accomplish this. The numeral 80 indicates guide-members secured tothe main frame 1, 1, on either side of the machine. Carried by these guides are vertically movable members 81 having secured to the upper ends thereof a horizontal bar 82, provided at its outer ends with upwardly-projecting lift fingers 83. These fingers are adapted to be moved vertically at a predetermined time by means of a-rock shaft 85 suspended beneath the main frame by suitable supporting-brackets 86. K tending horizontally from thisrock-shaft are rocker-arms 87, the outer ends of which are received between the sea of rollers 88 and 89 contained in the housing 90 secured to the vertically movable member 81.

Depending from therock-shaft 85 is a rocker-arm 91, the lower ends of which are forked as at 92, and extending transversely thereof, is a cross-pin 93 received in an elongated slot 94 arranged in the reciprocating-bar 95, the opposite end of which is pivoted to the rocking-beam 17 by which a re; clprocatlng motion is im arted to the bar 95. The slot 94is'offse toward the rear of the bar, forming an abutment 93', which, when the bar 95 is reciprocated, imparts a rockin motion to the rocker-arm 87, the latter -1mparting a vertical movement to the lift-fingers 83, serving to lift the cover vertically from the reciprocatin carriage and deposit the same.upon the ogs 77. 'Prior to this movement, however, a'cutter 96 carried b the vertically movable die 58 has severe the metal strips 35, permitting the 7 material to be moved vertically from the carriage.

To position accurately the material between the vertical standards ,76, I preferably arrange stop-pins 97. upon the main frame 1,1, and, to prevent the material from bulging when coming in contact with the stops 97, I preferably arrange a set of stop-fingers 98, which are secured to the rock-shaft 85. The upper ends of these fingers are bent inwardly as at. 98, and the outer end of the board assing to this position is received beneat the ends. of the rockingfin ers.

s observed in Fig. 8, the lift-fingers 83 .are beneath the cover about to be lifted a sufiicient distance to permit the rocker-fingers 98 being moved out of engagement with the box before the lift-fingers 83 are effective.

The severed metal strips 35, which reinforce the material about to be lifted are of such a length as to extend horizontally from the cover, and it is desirable to bendthem downwardly when the cover is being lifted. To accomp ish this, 1 preferably arrange a frame 99 secured at the base of the vertical standards 76, the outer ends of this frame being bent into substantially U-shaped form to receive the set-of rolls 100.

'As the cover is positioned at this the metal strips 35 are directly beneat the rolls 100; as the cover is moved vertically, the ends of the metal strips are bent downwardly by the rolls as the box is moved upwardly, shaping the metal strips as desired,

tiona'r platform, where they maybe suitably tledup for shipment.

To accomplish th1s,,1 arrange'on the reoint,

ciprocating carriage a collapsible table 101, Y

which is supported for vertical movement upon gsuitable parallel legs 102. This table 101 normally'rests upon 1 the reciprocating table, being of such a heightwhen down to pass beneath the covers being assembled upon the assembling-rack. To raise this table at predetermined times, a'pair of arms 103 are pivoted for horizontal movement,

as at 104, to the main frame. -These arms are connected by a cross-link 105 in such a manner as to be'moved simultaneously. Rollers 106 are secured to the inner ends of these arms, which are adapted to be moved into the path of the depending abutments 107 carried by the table 101, serving to lift the table to a vertical position at predetermined times.v To raise this table vertically, I arrange at the rear of'the main frame a ratchet-wheel 108 adapted to be actuated by a ratchet-pawl 10? carried by a rocker-arm 110.

Projecting laterally from the reciprocating carriage is an actuating pm 111, which engages the rocker-arm 110 eachtime the carriage completes a cycle, serving to rotate the ratchet-wheel 108, one notch at a time. A projection 112, Fig. 2, secured to the face of the ratchet-wheel engages the outer end of one of the arms 103, once every revolution of the ratchet-wheel 108, serving to move the rollers 106 into the path of the abutment 1'07 carried by the transverse table, causing the table to be lifted beneath the covlezrs now assembled upon the assemblingrac In order that the table may be held in a vertical position, while moving rearwardly with the covers, I preferably provide a pair of pivoted catches 113 arranged at the extreme rear of the reciprocating carriage. These catches are provided with notches 114 which engage the supports 102 of the transfer table holding the table in vertical position. The catches 113 are tied together with a connecting-link 115, whereby they are actuated simultaneously. To disengage the notches at the proper time to allow the table to collapse, a tripping-dog 116 carried by main-frame is adapted to engage the t e o iiter end of one of the catches 113, and a pin 117 extending inwardly from the main frame engages one of the supporting-legs 102 of the transfer table, causing the table to fall to a folded position. The covers carried by the table drop upon suitable stationary sup ports 118 projecting-upwardly from the ing-beam 16. This foot-lever 123 is held mam frame. I I

The-stack of covers are now in posltion .to be compressed and tied. To compress these, properly, preparatory to tying, T have arranged on either side ofthe main frame a pair of foldingpresser-arms 119, which are pivoted-to a vertically movable horizonar 120 received in slots .121, in the ports 118. The lower e ds of the arms 119 are bent inwardly, the inner ends thereof being connected by links 122 to a footlever 123 pivoted as at 124 to -the supportnormally in an u right position by spring .124, the springbeihg of sufficient tension to I hold the arms normally in their extended position. Springs 125 assist in causing the arms 119 to swing inwardly, as pressureis applied to the foot lever 123. The upper ends. 126 of the arms 119 are bent inwardly and adapted to engage the uppermost cover of the pile compressing the several covers together preparatory to being tied.

Operation.

Assuming that the feeding-hopper21'. is I filled with the several covers to be reinforced, the reinforcing bands 35 are initially fed through the first set of shaping rolls by hand, and the machine is given a sufficient movement to pass-one of the covers to be reinforced together with thereinforcing strips to the second set of forming rolls.

he machine isagain given a slight movement, sufficient to pass this board together with the reinforcing strips beneath the pressure and ,puncturing dies 53 and 58, where the metal strips are pressed and ierced, as

disclosed in Fig. 22. The machine is now.

neously with this movement the presser and punching dies 53 and 58 are brought together. Simultaneously with this move- 'ment the shearing-knife 96 serves to sever 'the reinforcing strip, which Is now beneath the assembling rack, from the continuous metal strips. The mechanism for actuating the lift-fingers 83 is so timed as to elevate at this timeFthe'now-severed reinforced cover vertically, where it is received and held between the spring-actuated dogs 77, and simultaneously with this movement, as explained, the outer ends of the reinforcing metal strips 35 are bent downwardly, forming detachin laps.

As the mac ine continues to operate, the several covers are passed through the different operations explained, and ate consecutivelyelevated to the assembling-rack. The vertically-movable transfer table carried by the reciprocating carriage is normally down in its inoperative position, in which position it is passed -'beneath the assembling-rack without disturbing the contents thereof. The reciprocating carriage, however, serves to actuate the ratchet mechanism, which in turn, at predetermined intervals, causes the arms 103 which are pivoted for horizontal movement to he brought into the path of the transfer-table 101, at such a time as-to cause it to raise vertically when beneath the several reinforced covers which are new stacked shilpment.

I aaeaem in the assembling-rack, this vertical movement serving to raise the stack above the spring-pressed fingers 77, which, when relieved of the load,retract, permitting the transfer carriage to carry the stack of covers rearwardly into re istration with the stationary receiving-table comprised of the stationary supports 118. I

As the transfer table reaches this position, suitable tripping mechanism carried by the reciprocating carriage co-operating wit 1 the stationary trip 116, unlatches the now vertically raised transfer carriage, which, in turn, is struck by the stationary actuating pins 117, causing the same to drop and deposit its load upon the stationary table,

the machine in the meantime continuing in its operation.

During v the re-assembling of the reinforced covers upon the assembling-rack, the

.operator (by manual means consisting of the ivoted arms 119 and the spring-actuated oot-lever 123) compresses the load deposited upon the stat-ionar table preliminary to tying the same su ciently for the t will thus be seen that I have constructed a machine for partially forming the metal reinforcing strips into the proper shape, feeding them past the stacked covers to be reinforced, passing the cover to be reinforced, and the artially formed reinforcing strips throu'gli a set of forming rolls, thence to a set of pressing and punchin dies, thence to an assembling-rack, and fina ly transferri the assembled reinforced covers to a stationary rack for bundling and Iglaim:
